Process for the preparation of phosphorous acid derivatives, characterized in that such phosphorous acid compounds are heated, characterized in that such trivalent phosphorus compounds are heated which have two organic radicals linked to the phosphorus atom in an oxygen, sulfur or nitrogen atom, and an aliphatic radical of lower molecular weight bound to the phosphorus atom in an oxygen or sulfur atom, with alcohols or mercaptans whose molecular weight is greater than that of the alcohol or mercaptan corresponding to the aliphatic radical of lower molecular weight, in whose operation a re-esterification occurs.
